I'm still a fan, to start with
Since installation back here: http://irishrailwaymodeller.com/showthread.php/4-Amiens-Street-Terminus?p=14759&viewfull=1#post14759
They've not given a moments trouble, bar some initial voltage issues which made them problematic to programme. Since then, DCC Concepts have 'updated' the motor, and branded it http://www.dccconcepts.com/catalogue/a/Point-Motors-Cobalt-iP-Digital
The new version is self-centred and handles the voltage issues better.
On the Peco point adaptations, yes, I use electrofrogs, which need a few 'tweaks'.
Here is how I do mine:
On the motors themselves, check the documentation (which is excellent) on the link above. It details how they wire up, how to control them, how to build a control panel with levels or buttons/leds and how to use them in an offset or in pairs for crossings.
I fitted all mine using the available foam pads, not a bother in 3 years and counting...
